Question 19

density is an example of a

a)chemical property

b)chemical change

c)physical property

d)physical change

An example of C) physical property.

The density is related to the volume and mass of a material. The higher the density the heavier the object.

Those properties which are visible without changing the matter's composition are called as physical property. The factor such as texture, color, odor, melting point, density, solubility, appearance, polarity, boiling point, and many others are considered as physical property.  

On the other hand, those properties which are witnessed after changing the state of the matter it is called as chemical property. It includes corrosive, radioactivity etc.

The change which produces new substance is called as chemical change whereas the change which doesn't produce any product is called as physical change.

dude really come on

explanation:

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
